The person who does the announcements at St a Pancras?

The, first announcer, A, is his voice normal? Do people record, besides youtube train announcements that I can purchase? http://m.youtube.com/watch?v=pSSB-rNsh8Q And for those who know who I'm talking about, what times does he work as I need to speak to him (he said he would get back to me) on either Sunday, Monday, or Tuesday Morn. His colleague does not work always at the time so does anyone know what times he works?
